Application tiled Fetrruary` 16, 1907. Serial No. 357,658.

To all -u'zom it may concern:

Be it known that I, MAX F. Annr. a citizen of the l'nited States, residing at NewiYorlt city, Manhattan, county and State of New York, have invented new and useful Improvements iii Rotary Pumps, of which thc following is a specilication. i

This invention relates to a rota-ry pump which is oi simple construction, cleanly in its operation, and is not apt to become rapidly worn by abrasion. The sand, slime, pulp and for similar purposes.

ln the accompanying drawing: Figure 1 is a vertical longitudinal section of my improved rotary pump, ard Fig. 2 is a cross section on line 2*?, Fig. 1.

The rotatable pump cylinder has hollowgudf." ll. l2 supported on bearings 13. Rotary motion is imparted to cylinder l0 directlyhyjhc driving belt ll that engages the circumference oi the cylinder, lthus dispensing with all intermediate power-transmittingmeans. To prevent displacement of the belt, the cylinder' may be provided with outwardly extending flanges 15. Within cylinder l0 there is iormed a partition 1li parallel to the heads thereof, and which divides the cylinder into a'n ingress chamber 17 andan egress chamber' 18. These chambers connect with eachother by a suitable number ot' peripheral openings 19 in partition 16. Chamber l17 coirnnunicates directly with the bore of the ingress gudgeon 11 and receives the material, to be pumped, through a fixed valve-controlled inlet pipe 20 projecting through said gudgeon into the chamber. Within chamber' 18 is fitted a spiral conveycr 2l having convolutes of gradually decreasing dlametcr. Oi these, the innermost convolute communicares directly with the bore oi the egress gudgeon 12. The fixed discharge pipe 22 of the pump connects with the outer end oi' gudgeon 12, to which it is coupled by a siuliing box 23.

Rotary motion being' imparted to the pump cylinder by belt 14, the material to he lifted is delivered by pipe 2O into chamber 17, from whence it passes through openings 19 into the outermost convolute oi' conveyor 2l: As the pump rotates, the material will illus he raised until itv is discharged iromthe innermost c'onvolutc of the conveyer into gudgeon 12,' and thence out. ol' discharge pipe 22.

lt will be seen that my improved pump is of simple construction, operates with great cleanliness and is not,

' apt to become rapidly worn.

I claim:

l. ln :1 rotary pump. a rotatable cylinder', a partition within the cylinder provided with peripheral perforations :and dividing the cylinder into an ingress and egress chamber. a hollow inlet ;'udgeon communicatin,"r with the ingress chamber. a hollow outlet gudgeon, and a spiral conveyer in the eci-ess chamber with the inert-ss chamber and at its inner coil with the outlet gutie'eon. substantially as specified.

i. ln a rotary pump. a rotatable cylinder. a partition within the cylinder provided with and dividingr the cylinder into an ingress and egress charnber. a hollow inlet gudeeon communicating' with the ine'ress chamber, a hollow outlet gudgeon, a spiral conveyei in `tbe egress chamber' that communicates at its outer coil with the ingress chamber and at its inner coil with the outlet gudgeon. and a fixed feed pipe entering the inlet gudgeon, substantially as specified.

In a rotary pump, a rotatable cylinder, a partition within the cylinder' provided witlrperipheral perfor-ations and dividing the cylinder into an ingress anti egress chamber, a hollow inlet gudgcon cominunicatinel with the' gress ehanrberja hollow outlet gutigeon, a, spiral eonveger in thevegress chamber that communicates at its outer coil vwith the ingress chamber and at its inner' coil with the outlet gudfreon, a fixed delvery'pipe', and means for coupling said pipe to the outlet gudgeon. substantiallyv as speci rien.

Signed by me at New York city, (Manhattan.) N. Y., this 15th day of February, 1907.
